STATES ROBERT A. BECKER, or rouenxnnrsrn, New YORK WIRE CONNEGTERApplication filed October is, 1928. Serial No. 313,286.-

This invention relates to a connecter for securing the meeting end ofwires, cables or rods together to form a strong mechaniijoint, such asemployed by power, light and signal installation, where it is desired tosecure together the ends of two single wires, the ends of strandedcables, or the ends of rods, in a quick, strong and adjustable mannerwithout twisting together, or by the use of solder, or welding.

The object of the invention is to provide a connector containing fewparts, simple of construction and application; strong, andhaving amaximum grip upon the wire, thus providing a connector havinglowelectrical resistance.

Another object being to provide a connecter, in which the usual nuts arenot employed, thus doing away with the objection to splitting of nuts,tearing of threads and the like.

Still another. object being to provide a connector having a long gripupon the wire, thushaving a large surface contact insuring goodelectrical contact.

Also providing means whereby one wire may be secured at a time withouthaving to secure both of the ends at the same time, thus allowing of thedevice being assembled to one wire or other article, before being attached to the end of the other wire.

lVith these and other objects in View, the invention consists in certaincombination and construction of parts as will hereinafter be fullydescribed and claimed, and also illustrated in the accompanyingdrawings, in which like figures of reference refer to correspondingparts in. all of the views, but

1t 15 to be understood that Shght Changes 'be inserted or removed fromthe connector may be made without departing from the spirit of theinvention.

In the drawings:

Figure 1 is a side elevation of the connecter, showing the same asapplied to the ends of two meeting wires. 7

Figure 2 shows a group view of the several parts which go to make up thedevice.

Figure 3 shows a longitudinal sectional closed in on the wire 15 toclamping means.

Figure 4: shows an end view of the device. Figure 5 shows. a crosssectional view takenon the line AA of Figure 1. Figure 6 shows an endview of portion without the threaded plug.

view ofithe connecter, illustrating the the body 7 Referring to thedrawings, the device comprises a body portion 10, here shown as beingmade from hexagonal material such as brass, but which may be of anysuitable shape in cross section and of any suitable material.

Said body portionlO, is formed with an axial bore extending its entirelength, but being tapered outward toward each end as shown bythe'numeral 11, the ends of said tapered portions being providedwith theinternal threads 12.

Within each of said ends of the body portion 10, is secured a wiregripping plug 13, which is formed with an axial bore 14: slightly largerthan the wire 15, so that it may easily be placed upon the end of the IWlI'e.

Said gripping plug comprises a body provided with the threads 16 adaptedto engage the threaded ends 12; a head integral therewith and providedwith flats 17 for the engagement of a wrench or other means ofoperating, and a tapered nose portion 18, of the same taper as theinternal taper of the ends of the body portion 10; said tapered nose 18being rendered resilient by a series of longitudinal slots or sawcuts19, so that as said plug is screwed into the end of the body portion 10,the tapered nose will be same against removal.

It will be thus be seen that the wire may by slightly backing out theplug to relieve the grip of the tapered nose, and also as the nose orgripping collet can be long owing to this construction, a long grip iseffected on the wire, yet the entire device is compact, and there are noloose bushing, or nuts.

Having thus described my invention, what I claim as new anddesire tosecure byLetters Patent, is:

grip and hold the p 5 end of the plugs.

A wire connecter of the class described, comprising a hexagonal bodyportion formed with an axial bore having a short portion of slightlylarger diameter than the wire, an enlarged and threaded opening in theends of said body portion, a tapered portion connecting said bore withsaid threaded ends, a clamping plug formed with an axial bore, athreaded body adapted to coaet with the threaded ends of the body poratapered andtslotted end formed-- tion, 7 thereon adapted to coact withthe tapered portion of the body bore to grip the wire,

and hexagonal heads formed on the outer hereof I aifix my signature.

In testimony,

ROBERT A.'BECKER.
